Composite transparent bar soap containing visible soap insert(s)

ABSTRACT

A composition and a method of preparing a solid, transparent/translucent moisturizing/cosmetic/personal cleansing bar having one or more visible soap inserts, wherein a transparent soap matrix surrounding the soap insert has an increased melting temperature of at least 55° C. to prevent melting the soap insert during manufacture, and to reduce deformation during storage and handling, increasing its hardness and durability, and substantially reducing the tendency of the bar to lose weight over time by evaporation of water by exposure to room temperature. The soap insert can have the same composition as the surrounding transparent matrix soap, having less water to provide at least a 3° C. higher melting point, and/or a small percentage of pigment or dye, for easy recycling of defective bars, without the need to separate the soap insert from the surrounding matrix soap.

FIELD OF THE INVENTION

[0001] The present invention is directed to a composite soap article formed from a transparent or translucent molten matrix soap material that is poured to surround one or more solid soap inserts, said inserts formed from a higher melting point soap composition that is visibly differentiatible from the surrounding transparent matrix soap composition due to a difference in opacity and/or color. In a preferred embodiment, the insert soap composition differs from the surrounding soap composition only by water content and/or dye and/or pigment addition—the insert soap composition having less water than the surrounding soap composition in a preferred embodiment, making the insert composition more opaque and having a higher melting temperature than the surrounding transparent matrix soap composition.

BACKGROUND OF THE INVENTION AND PRIOR ART

[0002] Composite, decorative soaps, sometimes called mosaic soaps, are well known in the art as evidenced by the Inui et al. U.S. Pat. No. 4,504,433. These composite soaps are formed by placing one or more solid pieces of insert soap, in the form of a decoration, design, or written material, into a mold, holding the insert(s) in position within the mold and then pouring a solution of a melted transparent soap to fill the mold, thereby surrounding the insert(s). The transparent soap is generally poured into the mold to surround the inserts at temperatures in the range of about 60° C. to about 75° C. and the transparent soap then is cooled to solidify, thereby permanently holding the soap insert(s) in position.

[0003] The soap inserts, also known as icons, can be formed from various soap compositions, generally about 85% sodium stearate and 15% water, making an opaque soap, or can be formed from various other compositions such that the icons or inserts will be visibly distinguishable relative to the surrounding transparent matrix soap composition so that the icons or inserts are clearly visible within the composite bar of soap. It should be understood that the terms “insert” and “icon” are used interchangeably herein, however, “icon” should not be understood to require the insert soap composition to be formed in any definite or predetermined shape or size. The insert or icon soap composition can be any predetermined or random shape or size.

[0004] These decorative soap bars are very appealing and attractive from a visual standpoint but have a number of drawbacks, some of which result from the substantially different soap compositions used for the icons or inserts as compared to the composition of the surrounding transparent soap material. During use, the higher dissolution rate of the clear soap results in an uneven wearing of the soap bar—the matrix or clear soap dissolves in water about two to three times faster than icons made of regular sodium stearate-based, opaque soap. Further, during storage, often there is chemical migration from the clear matrix soap into the inserts at the insert/matrix interface, resulting in the softening of the inserts. In addition, although the decorative soap bars are normally wrapped in a protective polymeric film, the clear matrix soap loses weight at a higher rate than the surrounded soap inserts, thus distorting the appearance of the decorative bar of soap.

[0005] Another common problem with such decorative soaps is from dye “bleeding” which results from dye migration from the soap inserts into the surrounding transparent matrix soap composition. Further, recycling of any defective or unsold soap bars is virtually impossible with extant decorative bar soaps due to the substantially different compositions for the insert and matrix soaps.

[0006] Mottola U.S. Pat. No. 5,217,639 discloses a decorative soap bar that includes an opaque portion and a transparent portion—both portions adjoining each other only along a single curvilinear shaped surface—wherein the opaque and transparent soap compositions differ only by including a solid pigment in the opaque composition. However, the melting points of both soap compositions are the same so that one composition melts partially when contacted with the other soap composition during manufacture so that detailed icons or inserts are impossible.

SUMMARY OF THE INVENTION

[0007] In brief, the present invention is directed to a decorative bar of soap including one or more internal soap inserts, in any desired shape, surrounded and completely encased by a transparent or translucent matrix soap composition, wherein the surrounding matrix soap composition has a lower melting point than the icon or insert soap composition.

[0008] In accordance with a preferred embodiment of the present invention, the soap composition used to form the icons or inserts can be the same as that for the surrounding transparent matrix soap composition with the exception that the icon or insert soap composition must, in any manner, be made to be visually distinguishable from the surrounding or matrix soap composition, e.g., the insert is made less translucent or less transparent than the surrounding composition by virtue of having less water; having an increased concentration of insoluble soap; having an increase in the carbon length of the insoluble soap; having higher boiling solvent(s); containing a dye or pigment; and/or having higher melting point surfactant(s), but otherwise may contain the same components as the surrounding matrix soap composition. By including less water in the icon or insert soap composition, the icons or inserts may become readily visually distinguishable from the surrounding matrix soap composition, in being more opaque than the surrounding matrix soap composition, and the icons or inserts have a higher melting point, being at least 3° C. higher, than the surrounding matrix soap composition when formed with the components described hereinafter. In accordance with another important feature of the present invention, the increase in melting point of the icon soap composition can be affected by an expedient selected from the group consisting of: (1) a lower amount of water; (2) an increase in the insoluble soap content; (3) an increase in the carbon chain length of the insoluble soap; (4) solvents having a higher boiling point; and/or (5) different surfactant(s) causing a higher boiling point in the icon soap composition.

[0009] The above and other aspects and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments, taken in conjunction with the drawing.

BRIEF DESCRIPTION OF THE DRAWING

[0010] The FIGURE is a graph that compares the hardness, in Newtons, of the preferred translucent/transparent soap composition of the present invention (Example 6—PREFERRED) to the same composition containing 17.7% by weight water, prior to dehydration (Example 6—FORMED).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The transparent/translucent matrix soap composition of the present invention includes polyhydric solvents, in an amount of about 15% to about 65% by weight, preferably about 25% to about 65% by weight, including (A) one or more polyhydric solvents that include at least three hydroxyl groups, in an amount of 5% by weight to about 40% by weight, and (B) one or more polyhydric solvents that include two hydroxyl groups, e.g., diols or glycols, in an amount of about 10% by weight to about 30% by weight. The transparent/translucent matrix soap composition contains about 4% to about 13% by weight water, preferably about 4% to about 12% water, most preferably about 7% to about 12% water, and preferably contains at least 1% by weight more water than the composition used to form the icons or inserts, with the icons or inserts having sufficiently less water than the surrounding composition so that the icons or inserts are visibly distinguishable from the surrounding composition.

[0012] The transparent/translucent surrounding matrix soap composition contains a final water content of about 13% by weight or less, preferably about 4% to about 12%, more preferably about 7% to about 12% water, to prevent melting and reduce deformation during storage and handling, increasing its hardness and durability, and substantially reducing the tendency of the decorative bar to lose weight over time by evaporation of water by evaporation.

[0013] Accordingly, one aspect of the present invention is to provide a decorative transparent/translucent moisturizing/cosmetic/personal cleansing bar that is more durable, has a relatively high melting point, and a lower water content than prior art personal cleansing bars, while maintaining clarity (transparency) for visibility of one or more internal shaped inserts.

[0014] Another aspect of the present invention is to provide a decorative transparent/translucent moisturizing/cosmetic/personal cleansing bar that is less susceptible to being deformed by heat and/or pressure and includes a combination of polyhydric solvents (1) having three or more hydroxyl groups; and (2) two hydroxyl groups, while providing a bar having a minimum amount of water (4-13% by weight) so that hydrolyzable bar components, such as antibacterial components, e.g., triclocarban (TCC), maintain more of their efficacy for longer periods of time.

[0015] A further aspect of the present invention is to provide a decorative cleansing bar having one or more visually detectable shaped inserts formed from a soap composition that approximates a surrounding transparent/translucent matrix soap composition, wherein the insert composition is more opaque, or otherwise visually distinguishable from the surrounding soap composition, but preferably dissolves in water at approximately the same rate as the surrounding soap composition.

[0016] Still another aspect of the present invention is to provide a decorative cleansing bar that includes one or more shaped icons or inserts that have a composition that differs from a surrounding transparent/translucent composition essentially only in water content and/or dye or pigment addition so that decorative cleansing bars that are imperfect during manufacture can be recycled easily either to an insert composition supply vessel or to a transparent/translucent matrix soap composition supply vessel, without separating the inserts from the surrounding matrix soap composition prior to recycling.

[0017] The transparent/translucent surrounding matrix soap composition of the present invention includes the following components, after manufacture, and may contain additional additives, such as antibacterial agents, dyes, perfumes, fillers, polymers, silicones, encapsulated materials, and the like: More Most Range Preferred Preferred Preferred % % % % water-soluble polyhydric 15-65 25-65 30-55 35-50 solvent(s), 3⁺-OH, e.g.,  5-35 10-30 15-25 17-22 glycerine, sugar alcohols, e.g., sorbitol and the like 2-OH, e.g., 10-30 15-30 20-30 22-27 propylene glycol, polyethylene glycol, dipropylene glycol monohydric alcohol, 0-4 0.5-3   0.5-2   0.75-1.5  e.g., ethanol soap  5-40  8-30 10-25 10-15 surfactant(s)  5-40  5-30  8-25 10-20 water  4-13  4-12  7-12 10-12

[0018] The term “soap”, for purposes of describing the “soap” component of both the transparent/translucent matrix soap composition and the icon or insert composition of the present invention, has the meaning as normally understood by those skilled in the art: monovalent salts of fatty monocarboxylic acids having a carbon chain length of from 12 to 24, preferably from 14 to 18 carbon atoms. These monovalent salts would normally be sodium salts, although some cations, such as K, Mg or alkanolammonium ions could be used. The preferred insoluble fatty acid soap is at least 90% by weight, more preferably at least 95% by weight selected from the group consisting of sodium myristate, sodium palmitate, sodium stearate and mixtures of any two or more thereof. Other insoluble soaps, particularly higher fatty acid insoluble soaps, can also be used.

[0019] The preferred surrounding transparent/translucent matrix soap composition of the present invention is melted and poured to surround one or more solid insert, shaped soap compositions.

[0020] The transparent/translucent surrounding matrix soap compositions of this invention can be prepared with reduced water content, for example, by using anhydrous polyhydric alcohols and/or anhydrous surfactants or by removing water from the composition initially formed with a higher water content.

[0021] Significant performance improvements for the transparent/translucent surrounding matrix soap composition are obtained by combining water-soluble polyhydric solvents having at least three hydroxyl groups (3⁺-OH) with water-soluble polyhydric solvents having two hydroxyl groups (2-OH). Significant performance improvements also are obtained by reducing the water content to a maximum of about 13% by weight, preferably in the range of about 4% to about 12% by weight, more preferably about 7% to about 12% by weight, most preferably about 10% to about 12% by weight water. The melting point of the matrix soap composition is increased to at least 55° C., which is above the temperatures that are expected to be reached during shipping and storage, thus avoiding melting and deformation of the decorative personal cleansing bars of the present invention.

[0022] Another benefit to the transparent/translucent surrounding matrix soap composition of the present invention is the reduction of weight loss. A cleansing bar containing about 20% by weight water loses about 17% of its original weight when exposed to room temperature (25° C.) for three weeks, whereas the decorative cleansing bars of the present invention, including a transparent/translucent surrounding composition with a water content of 10% by weight only loses about 7.5% of its original weight under the same conditions.

[0023] Surfactants

[0024] The transparent/translucent surrounding matrix soap composition of the present invention includes about 5% to about 40% by weight surfactants, preferably about 5% to about 30% by weight, more preferably about 8% to about 25%, most preferably about 10% to about 20% by weight surfactants.

[0025] The surfactant can be an anionic surfactant, a cationic surfactant, a nonionic surfactant, an ampholytic or amphoteric surfactant or a compatible mixture of surfactants.

[0027] The transparent/translucent surrounding matrix soap compositions of the present invention also can contain nonionic surfactants. Typically, a nonionic surfactant has a hydrophobic base, such as a long chain alkyl group or an alkylated aryl group, and a hydrophilic chain comprising a sufficient number (i.e., 1 to about 30) of ethoxy and/or propoxy moieties. Examples of classes of nonionic surfactants include ethoxylated alkylphenols, ethoxylated and propoxylated fatty alcohols, polyethylene glycol ethers of methyl glucose, polyethylene glycol ethers of sorbitol, ethylene oxide-propylene oxide block copolymers, ethoxylated esters of fatty (C₈-C₁₈) acids, condensation products of ethylene oxide with long chain amines or amides, and mixtures thereof.

[0029] Numerous other nonionic surfactants are disclosed in McCutcheon's Detergents and Emulsifiers, 1993 Annuals, published by McCutcheon Division, MC Publishing Co., Glen Rock, N.J., pp. 1-246 and 266-272; in the CTFA International Cosmetic Ingredient Dictionary, Fourth Ed., Cosmetic, Toiletry and Fragrance Association, Washington, D.C. (1991) (hereinafter the CTFA Dictionary) at pages 1-651; and in the CTFA Handbook, at pages 86-94, each incorporated herein by reference.

[0030] In addition to anionic and nonionic surfactants, cationic, ampholytic, and amphoteric surfactants can be used in the cleansing bars of the present invention. Cationic surfactants include amine oxides, for example.

[0031] Ampholytic surfactants can be broadly described as derivatives of secondary and tertiary amines having aliphatic radicals that are straight chain or branched, and wherein one of the aliphatic substituents contains from about 8 to 18 carbon atoms and at least one of the aliphatic substituents contains an anionic water-solubilizing group, e.g., carboxy, sulfonate, or sulfate. Examples of compounds falling within this description are sodium 3-(dodecylamino)propionate, sodium 3-(dodecylamino)-propane-1-sulfonate, sodium 2-(dodecylamino)ethyl sulfate, sodium 2-(dimethylamino)octadecanoate, disodium 3-(N-carboxymethyl-dodecylamino)propane-1-sulfonate, disodium octadecyliminodiacetate, sodium 1-carboxymethyl-2-undecylimidazole, and sodium N,N-bis(2-hydroxyethyl)-2-sulfato-3-dodecoxypropylamine.

[0058] Soap

[0059] The fatty acid soap used in both the transparent/translucent matrix surrounding soap composition and in the icon-insert soap composition of the present invention comprises sodium soaps. However, low levels of non-sodium soaps such as potassium, magnesium, and/or triethanolammonium (TEA) soaps are permissible. Such non-sodium soaps, when used, are preferably used at a level of from 0% to 10% by weight, preferably from 0% to 5% by weight of the surrounding soap composition.

[0060] Optional Ingredients

[0061] The transparent/translucent surrounding matrix soap composition, as well as in the icon/insert soap composition of the present invention also can contain optional ingredients well known to persons skilled in the art. Such optional ingredients typically are present, individually, from 0% to about 5%, by weight, of the composition, and, collectively, from 0% to about 20%, by weight, of the composition.

[0062] Suitable optional ingredients include dyes, fragrances and one or more antibacterial compounds(s), that are present in a sufficient amount to perform their intended function and do not substantially adversely affect the transparency of the composition.

[0063] Classes of optional ingredients include, but are not limited to, dyes, fragrances, pH adjusters, thickeners, fillers, viscosity modifiers, buffering agents, foam stabilizers, antioxidants, foam enhancers, chelating agents, opacifiers, sanitizing or anti-microbial agents, preservatives, polymers, silicones, encapsulated materials, and similar classes of optional ingredients known to persons skilled in the art.

[0064] Specific classes of optional ingredients include alkanolamides as foam boosters and stabilizers; gums and polymers as thickening agents; inorganic phosphates, sulfates, and carbonates as buffering agents; EDTA and phosphates as chelating agents; and acids and bases as pH adjusters.

[0065] Examples of preferred classes of basic pH adjusters are ammonia; mono-, di-, and tri-alkyl amines; mono-, di-, and tri-alkanolamines; alkali metal and alkaline earth metal hydroxides; and mixtures thereof. However, the identity of the basic pH adjuster is not limited, and any basic pH adjuster known in the art can be used. Specific, nonlimiting examples of basic pH adjusters are ammonia; sodium, potassium, and lithium hydroxide; monoethanolamine; triethylamine; isopropanolamine; diethanolamine; and triethanolamine.

[0066] Examples of preferred classes of acidic pH adjusters are the mineral acids and polycarboxylic acids. Nonlimiting examples of mineral acids are hydrochloric acid, nitric acid, phosphoric acid, and sulfuric acid. Nonlimiting examples of polycarboxylic acids are citric acid, glycolic acid, and lactic acid. The identity of the acidic pH adjuster is not limited and any acidic pH adjuster known in the art, alone or in combination, can be used.

[0067] In accordance with a preferred embodiment of manufacturing the decorative moisturizing/cosmetic/personal cleansing bars of the present invention, the solvents and surfactants used in the matrix soap composition are added in an open agitated reaction vessel at atmospheric pressure and at a temperature sufficient to melt the fatty acids, generally at least about 70° C., e.g., 70° C. to 80° C. The fatty acid(s) then are added, followed by raising the temperature to at least about 80° C., e.g., 80-90° C., prior to the addition of a neutralizing agent, preferably a sodium base, e.g., NaOH, in an amount sufficient to provide 100% neutralization of the fatty acids, to form the soap, in situ. It should be understood that the soap, i.e., sodium myristate, sodium palmitate, and/or sodium stearate, can be added in pre-manufactured form instead of being formed, in situ. At this stage of the manufacturing process, if the water content matrix soap composition of the mixture is above 13% by weight, the temperature of the reaction mixture is raised to at least about 90° C., preferably 90° C. to 100° C. to evaporate sufficient water to provide a matrix soap composition having 4-13% by weight water, most preferably about 10-12% by weight water. It should be noted that during the above-described water evaporation or dehydration step of the manufacturing process, a small portion of the propylene glycol or other relatively low boiling solvents may evaporate together with the water. However, it has been found in the following examples that only about 0.5-2.0% of the propylene glycol is lost via evaporation during the dehydration step, and such solvent evaporation can be compensated for by the initial addition of 0.5-2.0% extra propylene glycol or other relatively low boiling polyhydric solvents at any stage of manufacture.

[0068] It should also be noted that the above-described dehydration step is unnecessary if one or more of the solvents and/or surfactants is added in anhydrous form (see Examples 3, 4, 7 and 10). Further, the dehydration step can be carried out at much lower temperatures by using a sealed reaction vessel at a pressure below atmospheric (under vacuum).

[0069] As well known in the art, the more volatile optional ingredients, such as dyes, fragrances and monohydric alcohols, should be added to the composition after cooling the molten matrix soap composition, e.g., to 70° C. or below, so that the volatile components are not lost to evaporation.

[0070] The decorative cleansing bars of the present invention can be manufactured by adding the soap in sodium salt form, or the fatty acid(s) can be added together with a sodium base, such as sodium hydroxide to form the soap in situ. As shown in the following examples, the matrix soap composition of the decorative moisturizing/cosmetics cleansing bars of the present invention have sufficient clarity to provide at least 85% light transmission, generally 85-95% light transmission. The inserts or icons should have a light transmission that is visually distinguishable from the surrounding transparent/translucent matrix soap composition, e.g., at least 1% lower light transmission, or having a different color. In accordance with another important feature of the present invention, when the bars are frozen and then thawed (Freeze/Thaw), the clarity of the matrix soap composition remains at least 90%, preferably at least 95% of its original clarity compared to about 80% clarity after Freeze/Thaw of prior art transparent soap compositions containing 17.7% water (see Example 6—PREFERRED vs. Example 6—FORMED). The following examples show the surrounding transparent/translucent soap compositions in percentages by weight of materials added to an agitated reaction vessel designated as “ADDED”; the composition formed from the materials added, designated “FORMED”; and the final composition after removal of water, if any, designated “FINAL”:

[0071] In the following examples of transparent/translucent matrix soap compositions, when the transparent/translucent matrix soap composition is made in situ by reaction of fatty acid(s) with a caustic solution, e.g., NaOH, it is preferred to add the caustic solution before the addition of the fatty acid(s) to prevent formation of gels or lumps, which would increase manufacturing time. It has also been found that color degradation is minimized by adding any sorbitol, or other non-reducing sugars containing at least three hydroxyl groups, only when the percent free fatty acid(s) is in the range of about 0.1% to about 2%, preferably in the range of 0.2% to 1.5%, more preferably in the range of 0.5% to 1.0% free fatty acid(s), based on the total weight of free fatty acids and neutralized fatty acids. The following is the preferred sequence of addition:

[0072] 1) Mix the non-sorbitol polyhydric solvent(s), e.g., propylene glycol and glycerine and the surfactant(s);

[0073] 2) Raise batch temperature to 70 to 80° C.;

[0074] 3) Add less than the required amount of the caustic solution needed to fully neutralize the later-added fatty acids, e.g., about 95% of the required amount of caustic solution, e.g., NaOH;

[0075] 4) Add the fatty acids, ensuring that the temperature remains above about 80° C. but below 100° C.;

[0076] 5) Analyze for free fatty acid, e.g., titrate with NaOH, using an indicator, such as a dye, and adjust, if required, to 0.1 to 2.0% by weight, preferably 0.2 to 1.5% (most preferred 0.5% to 1.0%) based on the total weight of free fatty acids and neutralized fatty acids, as lauric acid, adding more caustic solution or more fatty acid, e.g., stearic acid;

[0077] 6) Add the sorbitol solution, if sorbitol is one of the polyhydric solvents, and mix well;

[0078] 7) Start the water evaporation step, e.g., by raising the temperature of the batch to about 99 to 102° C. with good agitation while preventing the batch from boiling. Of course, water removal under reduced pressure would require lower temperatures, the temperature depending upon the degree of applied vacuum;
